In this activity, learners will create their own coral polyps - the basis for a coral reef.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this outdoor activity, learners build bird nests and place them in the activity area, then play the role of naturalists as they try to locate each other's nests.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this outdoor game, learners role play populations linked in a food chain.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta o en línea.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

By playing a card game similar to "Go Fish," but based on the stages of metamorphosis, learners will be able to see how insects change in form as they grow and will consider the advantages of undergoi

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.
